The fourth radiation element is coupled to the third radiation element. The fifth radiation element is coupled to the third radiation element. The fifth radiation element is at least partially surrounded by the third radiation element and the fourth radiation element.

Antenna structure and electronic device

An antenna structure includes a loop radiation element and a first radiation element. The loop radiation element has a first end and a second end. A feeding point is positioned at the first end of the loop radiation element. A grounding point is positioned at the second end of the loop radiation element. The first radiation element has a first end and a second end. The first end of the first radiation element is coupled to a first connection point on the loop radiation element. The second end of the first radiation element is open. The antenna structure covers a first frequency band and a second frequency band.

Antenna structure

An antenna structure includes a ground element, a feeding radiation element, a first radiation element, a second radiation element, a third radiation element, and a switch circuit. The ground element provides a ground voltage. The feeding radiation element has a feeding point. The feeding radiation element is coupled through the first radiation element to the second radiation element. The third radiation element is coupled to the feeding radiation element. The feeding radiation element is disposed between the first radiation element and the third radiation element. The switch circuit selectively couples the second radiation element to the ground voltage according to a control voltage. A slot is formed and surrounded by the ground element, the feeding radiation element, the first radiation element, and the second radiation element.

An antenna system includes a first antenna, a second antenna, a third antenna, an isolation metal element, and a nonconductive support element. The isolation metal element is disposed between the first antenna and the second antenna. The third antenna defines a notch region. The second antenna at least partially extends into the notch region. The distance between the third antenna and the second antenna is from 1 mm to 10 mm. The first antenna, the second antenna, the third antenna, and the isolation metal element are all disposed on the nonconductive support element.

Antenna system

An antenna structure includes a feeding radiation element, a first radiation element, a second radiation element, and a third radiation element. The feeding radiation element has a feeding point. The first radiation element is coupled to a first connection point on the feeding radiation element. The first radiation element includes a bending portion. The second radiation element is coupled to a second connection point on the feeding radiation element, and is adjacent to the bending portion of the first radiation element. The second radiation element is not parallel to the first radiation element. The third radiation element has a grounding point, and is coupled to a third connection point on the feeding radiation element. The third radiation element includes a first protruding portion and a second protruding portion. The first protruding portion and the second protruding portion of the third radiation element extend in different directions.
